When considering a patient with a transtibial amputation who presents with weak adductors, the standing position that the lower extremity might favor is abduction. This occurs because weak adductors are unable to exert sufficient strength to pull the limb towards the midline of the body. Consequently, the weight of the body and the lack of effective adductor muscle control can lead to the lower extremity being positioned further away from the midline, resulting in an abducted stance.

In individuals with weak adductors, the inability to stabilize the limb effectively can cause the leg to drift away from the body, promoting a stance characterized by abduction. This position can also potentially create compensatory strategies during standing and mobility, as the body finds ways to maintain balance and posture with diminished muscle strength. Understanding the muscular dynamics at play is crucial for formulating appropriate therapeutic interventions and ensuring optimal alignment and stability for the patient.
